There is many parameters needed to measure while calibrating the spectrum analyzer. The automated calibration used on the spectrum analyzer with modular programming and the GPIP bus technology can complete the measurement quickly,accurately and easily. The experiment data shows that the system is stable and reliable,the time-consuming and efficiency is proved. By correcting the output level of signal generator,the error is reduced to the least and the accuracy and accuracy of calibrating result is ensured.
